Figure 5.
Temperature dependence of photosynthetic parameters for wild-type (A) and PEPC mutant (B) A. edulis measured under 0.3 mbar O2. Shown are internal conductance in the mesophyll for wild type, gwt (the initial slope of A/Ci curves), the internal conductance in the mutant, gmut, and the calculated liquid phase-diffusive conductance in the mutant (gbs) and maximal CO2 assimilation rate (Amax). C has Amax from A and B plotted in Arrhenius axes (the slope equals −Ea/R). Values of JO2-net measured under saturating CO2 (data not shown) were similar to values of Amax.
